A bakery sells cookies (x) for $1.50 each and muffins (y) for $2.50 each. A customer buys at least 5 items, and spends no more than $15. The system of inequalities to model this situation is
1.5x + 2.5y ≤ 15
x + y ≥ 5
Can a customer buy 4 cookies and 5 muffins? Why or why not?
No, it will cost too much money.
